SULKY-PLOW.

SPECIFCATION forming part of Letters Patent No. 332,301, dated December15, 1885.

Application tiled May 5, 18H4. Sei-inl No. 130,391. (No model.)

To all whom it may concern.'

Be it known that I, WILLIAM STRAICua citizen of the United States,residing at Elmira, in the county of Ghemung and State of New York, haveinvented certain new and useful Improvements in Sulky-Plows; and I dodeclare that the following is a full, clear, and exact description ofthe invention, such as .will enable others skilled in the art to whichit belongs to make and use the same.

The object of my invention is to make a sulky-plow adapted to work onflat land and side hills, and to do perfect work in either case, theplows being adjustable to run at the desired depth, to cnt awider ornarrower furrow, and to work in a proper position, making the standardvertical either on a side hill or when one wheel is in the furrowand theother wheel raised upon the land.

My invention consists of two plows, one being right-hand and the other aleft-hand plow mounted upon a revolving and oscillating shaft carryingcolters or jointers, said plows being adjustable, as to depth, to andfrom the land, and so as to bring theplows into proper position eitheron a hillside, on flat land, or when either wheel runs in the furrow,and also in other devices and combinations, all of which will be fullyunderstood by the following description and claims.

In the accompanying drawings, Figure 1 is a side view showing therevolving shaft with the plows and colters mounted thereon, and otherparts connected therewith, the relative position of the wheels beingindicated in dotted lines. Fig. 2 is a top view of the machine. Fig. 3is a rear view. Fig. 4 is a detached front View of the draw-head andparts connected therewith. Fig. 5 is a detached view showing the leverby which the plows are rotated and the adjustable notches for lockingthe lever. Fig. 6 shows the attachment of the journal-arm to the axle S.Fig. 7 is a vertical section through the rot-ating shaft and heels ofthe plow-standards on the line x, Fig. 8, which is a horizontal sectionshowing the way in which the standards are attached to the shaft A so asto allow the plows to be swung into position.

Fig. 9 is a detached view of joint between the adj ustahle journalarmsand the axle. Fig. 10 is detached view of a jointer attached to theplow-standard. Fig. 1l isa detached View of the seat and its lever anddog for tilting and locking the same. Fig. 12 is a section through theheels of the braces b of the plow-standard.

In the construction of my sulky-plow I make an arched axle, S, withadjustable wheelspindles O for the wheels R, as shown in Fig. 3. Thesewheels are inclined inward at the bottom, and one wheel is intended torun in the furrow, treading close to the land side while the other wheeltravels on the land. ln this position the furrow-wheel runs clear anddoes not chafe against the land. By this arrangement of the wheels theupper one runs in a perpendicular position while the lower wheel isinclined,and upon 'reversing the plow the position of the wheels isreversed. On a side hill the pole is naturally carried higher than whenplowing on level land. and by raising the pole the arch of the axle isthrown backward, and the front of the wheels are gathered inward, andthe lower wheel,by running inthe furrow on the corner of thetire,inclines the machine to run toward the land. By means of thewheel-spindles O the wheels may be set wider apart or nearer together,according to the width of furrow desired to cut.

Upon the axle S is mounted a revolving and oscillating horizontal shaft,A, carrying two plows, T and r1"-one right and the other left hand-onthe standards B and B, having rear braces, b and b', as shown in Fig. l.Attached to these standards are two colters, D and D', or in place ofthe colters two jointers, D, Fig. l0, when it is desirable to employjointers. By means of this revolving shaft either the right or left handplow is easily brought down into working position, and enables themachine to plow back and forth, either on a side hill or on flat land;but in reversing the sulky we change the position of the wheels andbring the upper one on the lower side, either on the hillside or on flatland, changing one wheel from the furrow to the land, and the other fromthe land to the furrow. The seat-bar N is pivoted in front and connectedto the lever I by support W, which is provided with a spring dog, c, andratchet w, by means of which the seat may be tilted to the right or leftand brought into proper position, Whether the right or the left wheel isin the furrow. The plows are raised and lowered l by means of thecrank-lever K, which is connected to lever I by means of link t', andprovided wifh dog 7c, Fig. l. This lever I is pivoted to the arch of theaxle S, and the Weight of the driver in his seat helps to counterbalancethe weight of the plow. A flat bar, Y, holds the revolving shaft A inplace, the bar and shaft both passing through the axle.- arch and theloop z, which is bolted to the under side of the platform, leaving thebar and shaft to oscillate freely up and down in said loop and arch..This bar Y carries a vertically-slotted guide, g, in which the lever Iplays up and down, thus keeping the plows from twisting. The rear end ofbar Y is bolted to a'bracket on the front partlof the arch F. Thedraw-head p is attached to the front end of the shaftvA, and the upperend of the drawhead rests in a notch or slot in the front end of bar Y,to keep the draw-head from turning when shaft A is revolved. The frontend of shaft A has a j ournal-box, q, attached to bar Y, as seen in Fig.4, and the rear end of said shaft has a box, t, Fig. 5. The platform dis supported 011 the braces e, and the pole M is bolted to the top ofthe platform, as seen in Fig. l. A crank-lever, K, has a shaft about onefoot in length, working in boxes on the top of the platform, the leverbeing at one end of said shaft and the crank-arm K being at the other.This crank-arm K, by means of link i, is connected to lever I, which ispivoted to the arch of the axle, and the rear end of lever I isconnected to arch F, so that the driver, by moving lever K, can readilyraise or lower the rear end of shaft A, thus raising or lowering theplows at pleasure.

In a reversible plow, where first one horse and then the other isbrought into the furrow, the horses sometimes crowd in going in onedirection and then pull apart in going in the opposite direction. Tocompensate for this change it is necessary to make the plowsindependently adjustable, in order to swing them to or from the land.The plow-standards B and B are adjustably attached to the rotary shaft Aby means of the mechanism shown in Figs. 7 and 8, so as to be swung toand from the land, the heels of braces b being slotted laterally, asshown in Fig. l2, and attached to the flattened end of the shaft A by aset-bolt, which is easily moved. The shaft A and plows are rotated vbymeans of lever U, which is held in working position by the adjustablenotch or lever-lock f upon J, the arch F. This adjustment compensatesfor tilting the frame and wheel and also for ch anging the depth of thefurrow.

Instead of a colter, D, the jointer D may be used whendesired.

I do not claim, broadly, a sulkyor wheel plow with thewheel-spindles-inclined so as to cause the wheels to incline inward atthe bottom or upon the ground, for I am aware that wheels have been setin that manner heretofore; but what I do claim is the use of wheels setin that manner, in combination with a rotating or `side-hill plow,because in such combination there is a special use and I obtain specialadvantages not obtainable by the use of this feature in ordinarysulky-plows.

Having thus describe-d my invention, what I claim is l'. The bar Y,having a box at each end thereof, the shaft A, and draw-head1?, all oscillating vertically, substantially as set forth.

2. In a side-hill 'or revolving plow, the standards B B', provided withmeans for .separate or independent lateral adjustment upon their shaftor axis, whereby either plow may be set with its point to or from theland, substantially as set forth.

3. In a revolving plow, the standards B B', in combination with the axleand wheels, and an adjustable locking device, whereby the plow-standardsmay be locked in a vertical position while either wheel runs in the furrow, substantially as set forth.

4. In a revolving plow,the adjustable notch or lever-lock f upon theslot-ted arch F, in combination with the standards, for the purpose ofstopping the lever U in proper position when the plows are reversed,substantially as set forth.

5. The rocking lever or bar I, pivoted upon the arch of the axle S, incombination with the seat support W and seat-bar N, for the purpose ofbringing the weight of the driver to assist in raising and lowering theplows, substantially as set forth.

6. The combination of the crank-lever K, having arm K,connected bylinkt' to lever I, which is pivoted to arch S. of the axle and also tothe seat-support W, for the purpose of raising and lowering'the plowsand holding them in working position, substantially as set forth.

7. The combination, with the bar Y and rocking lever I, of the slottedguide g and plow-shaft A, for the purpose of holding the plows andpreventing them from twisting, substantially as set forth.k

8. In combination with a side-hill plow, the inclined wheel-spindles,for the purpose of inclining the wheels inward at the bottom,
